The device may then transmit a scheduling request during the random access time period. In some cases, the device may transmit the scheduling re- quest using frequency resources also associated with random access trans- missions. In other cases, the device may utilize resources that are not associ- ated with random access. The determination of which frequency resources are used may depend on the length of the DRX. That is, if a device has been in a sleep mode for a long time, it may use random access frequency re- sources that are associated with a more robust transmission configuration.
